I spend my summer holidays at my granny’s. There are many things there to do. What I did most of the time - I swam in the sea and sunbathed. Sometimes I made a fire with my friends at the seaside and cooked potatoes there. It was wonderful. We told anecdotes to each other, and did everything we wanted. I also got used to walk alone in the forest.
When August was coming to its end, I went on a small voyage by ship. The ship name was “Sevastopol”.
But this summer wasn’t for me only sugar and honey. I have passed through the graduating exams after school and entering exams in the university. So the bigger part of my summer vacations I spent sitting with the books. Of course, it was not interesting, but I’m glad that I did it because now I’m a student of the best university in our country.
11 2/3 км/ч
Пошаговое объяснение:
Расстояние, которое проплывает катер, равно 35*3 = 105 км.
Против течения такое расстояние, согласно условию, катер проходит за 4,5 часа, значит, его скорость равна 105:4,5 = 23 1/3 км/ч.
Тогда скорость течения реки равна 35 - 23 1/3 = 11 2/3 км/ч.
